Band model of a p-type semiconductor before (a, c) and after adsorption of the donor (b) and acceptor (d) gas molecule; EV, EC: bottom and top of energy gap; EA: acceptor level; EF, EFads: Fermi levels of semiconductor and adsorbate; LUMO, HOMO: lowest unoccupied and highest occupied molecular orbitals; EVAC: electron energy in vacuum; (e) temperature dependence of electric current flowing through SbSI nanowires in O2 (blue-green square), H2 (green square), and vacuum (pink square) (, ). Blue and red lines represent the fitted (1) in ferroelectric and paraelectric phases, respectively. The arrows show Curie temperatures. Values of fitted parameters are given in Table 1.
